192-acre lake near Québec. The lake tops out around 59 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. Here is how the season plays out for each species, straight from the data behind the map.
The drawn water covers 192 acres wrapped in 2.7 miles of bank. At index 1.4 the outline is almost a bowl — read the depth changes, not the shoreline. 37% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. End to end it runs roughly 1.2 mi, about 0.4 mi across. It sits in Les Appalaches MRC. If the bite dies, Lac Noir is 3 mi to the southeast.

Come spring, look for brook trout tight to the bank in 2 to 15 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 3 to 20 ft. Start at Main-lake point. It's a point holding about 6 ft of water and rates prime come spring. Prime time lands in early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm is the honest summer answer here.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 2 to 15 ft | dawn & dusk | Main-lake point (6 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 10 to 30 ft | dawn & dusk | Break off the point (5 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Automne | 2 to 15 ft | midday & dawn | Main-lake point (6 ft) | Small spoon (orange), Spinner |
| Hiver | 3 to 20 ft | dawn | Break off the point (5 ft) | Small jigging spoon, Tungsten jig + plastic |
Spring lake trout on Lac de l'Est hold shallow, usually 10 to 40 ft. By summer they slide out to 18 to 59 ft, and by winter most fish are in 15 to 59 ft. The chart's best answer is Deep basin — deep basin, 58 ft, prime for summer. Prime time lands in early morning. The summer box starts with a white tube jig (deep) or a magnum spoon on downrigger.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 10 to 40 ft | dawn & dusk | Main-lake point (6 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Été | 18 to 59 ft | dawn | Deep basin (58 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Automne | 10 to 50 ft | dusk & dawn | Main-lake point (6 ft) | Heavy casting spoon, Jigging rap over reefs |
| Hiver | 15 to 59 ft | dawn | Deep basin (58 ft) | White tube jig, Airplane jig |
When the water first warms, rainbow trout slide up into 5 to 20 ft. By summer they slide out to 8 to 30 ft, and by winter most fish are in 8 to 40 ft. If you only fish one area, make it Main-lake point: a point around 6 ft that scores prime in spring. In summer the feeding windows fall in early morning and the evening. Keep a dodger + spoon (deep troll) or a flutter spoon rigged through the warm months.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 5 to 20 ft | dawn & dusk | Main-lake point (6 ft) | Inline spinner (silver), Small spoon |

| Automne | 10 to 35 ft | dawn & dusk | Main-lake point (6 ft) | Casting spoon, Jerkbait over shoals |
| Hiver | 8 to 40 ft | dawn | Break off the point (5 ft) | Jigging spoon, Tube jig (white) |
The spring pattern is a shallow one: brown trout in 3 to 25 ft. Midsummer fish sit out in 18 to 59 ft before dropping to 5 to 35 ft for winter. The spot to know is Deep basin, a deep basin in about 58 ft of water that rates prime for brown trout in summer. Plan around after dark and early morning in the warm months. Summer baits: a spoon at the thermocline or a deep stickbait (night) gets it done.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 3 to 25 ft | dawn & dusk | Main-lake point (6 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |

When the water first warms, landlocked salmon slide up into 1 to 15 ft. By summer they slide out to 18 to 59 ft, and by winter most fish are in 10 to 40 ft. If you only fish one area, make it Deep basin: a deep basin around 58 ft that scores prime in summer. In summer the feeding windows fall in early morning and the evening. Keep a dodger + streamer down deep or a thin spoon on lead core rigged through the warm months.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 1 to 15 ft | dawn & dusk | Main-lake point (6 ft) | Streamer flies (Grey Ghost) off boards, Thin spoon (Mooselook style) |

Deep basin is the standout, a deep basin at roughly 58 ft, rated prime for summer lake whitefish. Time it for early morning. You won't need more than a blade bait vertical or a small jigging spoon most summer days.

|---|---|---|---|---|
| Printemps | 15 to 45 ft | midday & dawn | Break off the point (5 ft) | Small jig + waxworm, Blade bait (small) |
